It looks like this So the least common multiple of 4 and 10 is 20 Example Find the least common multiple of 6 and 15 The multiples of 6 are 6 12 18 24 30 and the multiples of 15 are 15 30 The first match is at 30 So the least common multiple of 6 and 15 is 30 More than 2 Numbers 24 31 and51 2 4 3 1 a n d 5 1 Step 3 Multiply these integers to get the LCM 24 31 51 240 2 4 3 1 5 1 240 So the LCM is 240 Lcm calculator finds the least common multiple of given numbers Our lcm finder can find lcm by prime factorization division lists multiple methods with steps
If we write out common multiples of numbers the first of these is called the least common multiple For example look for the common multiple of the numbers 2 and 5 Multiples of 2 2 4 6 8 10 12 14 Multiples of 5 5 10 15 20 Common multiples of 2 and 5 are 10 20 and so on LCM by Prime Factorization Method LCM using Division Method LCM by Listing Method We can find out the common multiples of two or more numbers by listing their multiples Out of these common multiples the least common multiple is considered and the LCM of two given numbers can thus be calculated
